Day 9.136: Bendy bones?

The instructions said to clean them and then soak them in vinegar "overnight or longer".

We opened the jar and tried the bendiness a few times, but it took until the other day - about five weeks - for the biggest bones to pass the test:

I suppose that qualifies as "overnight or longer"!
